Preparation method of ornidazole gastric floating tablets and use thereof

Abstract

The invention discloses a preparation method and applications of gastric floating tablets containing ornidazole, belonging to a novel technical field of medicament and relating to a novel medicament form of ornidazole. 1. The gastric floating tablets are used to treat a plurality of diseases caused by bacteroides fragilis, bacteroides distasonis, bacteroides oval window, etc.; (2) oral cavity infections: pericoronitis, periapical periodontitis, pericoronitis, acute ulcerouse gingivitis etc.; (3) gynae infections: endometritis, myometritis, oviduct or ovarian abscess, pelvic cavity soft tissue infection, haemophilis vaginitis etc.; (4) surgical infections: wound infection, abscess of epidermis, bedsore ulcerouse infection, cellulites, gas gangrene etc.; (5) brain infections: meningitis, brain abscess; (6) septicaemia and severe general infections etc. 2. The gastric floating tablets are used to prevent infections before an operation and treat anaerobic infections after an operation. 3. The gastric floating tablets are used to treat urogenital canal trichomonas and giardia lamblia infections, such as trichomoniasis etc. 4. The gastric floating tablets are used to treat alimentary system amebiasis, such as amebic dysentery, amoebic liver abscess etc. The new medicament form is characterized in that the surface thereof is hydrated into gel after contacting with gastric juice at body temperature so as to cause volume expansion because the gastric floating tablets contain a plurality of hydrophilic macromolecule materials. Weight of the tablets is less than floating force of the gastric juice, so the tablets float on the gastric juice so as to prolong time in a stomach.
